Obama appeared Tuesday in an episode of "Between Two Ferns With Zach Galifianakis," a recurring comedy sketch on the Funny or Die website. Maybe it was just good prep work by his aides, but Obama's grasp of the "Two Ferns" conceit — the mutual antagonism between host and guest — suggested that he was actually familiar with the cringe-worthy series.

The president was on "Two Ferns" ostensibly to promote the Affordable Care Act and urge people to sign up for a health plan at HealthCare.gov, the new federal insurance-buying site. And it's not unusual for a president or first lady to enlist the help of a pop-culture kingpin to advance the White House's agenda, whether it be appearing on a late-night show or a daytime TV gabfest.

But "Two Ferns" is hardly the "Tonight Show." It's aimed not at the masses but at a niche: people who delight in watching an inept talk-show host fail while his guests squirm in discomfort. It's an "I Love Lucy" bit done again and again with different guest stars, with an extra helping of irony (Is Galifianakis making fun of himself or of celebrities desperate enough for exposure that they'll appear on a sad-sack, cable-access program?).

In short, it's for the young and disaffected — the hipster demographic.

Granted, as the end of Obamacare's open enrollment period approaches, that's one segment of the population likely to still be uninsured. He specifically reached out in the video to "young invincibles" — young people who "don't think that they can get hurt," as Obama put it — to sign up online, by phone or in person by March 31. The more young people who sign up, the better the risk pool will be for insurers, which translates into lower premiums next year (or more likely, smaller premium increases).

This being "Two Ferns," however, Galifianakis subtly mocked the president's sales pitch, mumbling "Is this what they call 'drones?'" as he massaged his temple. Although it was funny, I couldn't help thinking that I was laughing at Obama, not Galifianakis.

If Obama knew what he was getting into, then kudos to him for being much, much edgier than the average commander in chief. But then he's considerably younger than most of his predecessors, so maybe that shouldn't be a surprise.

The Supreme Court's surprising decision last week to hear a new challenge to the Affordable Care Act has once again focused attention on Chief Justice John Roberts, who cast the deciding vote in a 2012 decision that saved Obamacare from being declared unconstitutional. Many court watchers...

When the House GOP authorized a lawsuit accusing President Obama of overstepping his authority, the rationale it offered was a head-scratcher: the administration's move to delay the employer mandate, a requirement that House Republicans unanimously opposed.

In what may be a hopelessly quixotic effort, supporters of the federal Children's Health Insurance Program are trying to persuade Congress to renew its funding almost a year in advance — and in a lame-duck session. Nevertheless, lawmakers ought to heed that call. The program plugs a...

The lawsuit the House GOP filed against President Obama on Friday opened a new front in the attack on the 2010 healthcare law, this time targeting the subsidies that reduce deductibles, co-pays and other out-of-pocket expenses faced by lower-income Americans. According to the complaint, the...

One of the loudest complaints about the policies sold through Covered California, the state's new health insurance exchange, is that they provide access to far fewer doctors than promised. On Wednesday, state regulators finally confirmed and quantified the problem with respect to two leading...
